Caitlyn Jenner's arrival was one of the moments of 2015 - and now it's emerged she may have been inspired by Amazon's award-winning series Transparent.

Transparent follows the Pfefferman family as they deal with the discovery that their parent Maura (Jeffrey Tambor) - formerly Mort - is transgender.

"We heard directly from Caitlyn Jenner - who obviously was the most public trans woman coming out at the time - that the show affected her and her coming out," Amy Landecker - eldest sibling Sarah Pfefferman - told Digital Spy.

"I think people have been able to use Transparent as a topic of conversation, and a way to open up communication to each other around this issue.

"I mean, the movement's just beginning - there's definitely a trans civil rights movement that is in full swing. Especially in the States, there's a full fight on a daily basis.

"I mean, transgender people are murdered at a higher rate, they have a higher poverty rate, higher suicide rate... and now there's laws being introduced to keep them from being able to use the bathroom that they want.

"So this is just the beginning of a conversation and a fight but I know we're all really proud of being a part of that conversation, and sparking that conversation."

"Nobody is egotistical with their head up their ass and thinking our shit doesn't stink because people are recognising the show - and so that makes us somehow better than everybody else because we won a Golden Globe and some Emmys.

"It's just not the case. There's nobody on the show that's wearing rose-tinted glasses about success and about what that means. Because it doesn't mean a f**king thing - it just means we're grateful."

Landecker though is confident that season two of Transparent will continue to impress - in fact, she thinks it's better than the first.

"It's the sequel - it's like Magic Mike XXL... it's even bigger and better! Because season one was so well received, I think everyone felt a creative mandate to push ourselves creatively. So I feel like it's even better."
